I remember seeing police call boxes on light poles in many cities.

Cities had massive networks of telephone lines to street corner call boxes. I wish someone would compile a history of such systems.
Philadelphia's was owned and maintained by the city govt itself (along with the fire alarm boxes). I read that NYC's was built under contract with NY Telephone very early in the 20th Century. There were articles in the NYT 100 years ago about how the presence of call boxes saved time to capture a burglar. Of course, 100 years there were far less burglaries and robberies despite the city being extremely crowded. The few that occured were newsworthy enough to make the front page of the NYT in those days.
The former Phila telephone admistrator "the chief" was one of the types who stayed on the job forever and knew every nook and cranny of an ancient system. When he finally retired the newspaper covered it. I wished I had the chance to meet and interview him before his passing.
